How to factory reset EC800E-CN?

Hello,

May I know how to perform factory reset for EC800E-CN?

I tried some commands, qprtpara, and nvrestore but no success.

ATZ0 works but APN(AT+CGDCONT) and some other information remains.

Also tried to flash firmware but no difference.

Thanks.

Hi @jh11111
You can try the AT&F command, in addition, it is generally not recommended to restore factory Settings directly, you can adjust for the required options.
